I did too on my grow but i dont think it effected my growth to much im right under 30 days I over watered and fucked a feed up but I flushed as much as I could and let my soil dry for 5 days and they seem happy now.
Another mistake on my part was not using a soil with lime. I do not PH adjust water so I bet my soil PH is fucked. Also I over watered because I did not use perlite throughout the soil. Over watering and a PH that has no doubt moved far from 6.5
It's time to get my bluelab out and stop fucking around.
